. new and useful Improvements in Numbering and Dating Machines, of whichthe following saclear, fu'll', andeggach description.

' Thisinventionrel "tes in general to numbering machines, a dparticularly that class r ot machines,

of numbering machines known as dating Its ob ect 1s to improve andsimplify the'eonstruction of such machines, to secure improved'operationand use of such. a machine, and particularly with referenceto improvedmeans for advancing thenumber wheels and for attaching printlng platesadjacent to the functioning characters of said wheels, ,and further forproviding improved means for holding the frame carrying the numberwheels in locked position during the attachment of saidplates and motherspecific improved constructions of machine, as

set forth'in the claims. In the drawings, Figure 1 is'a front elevatipnof my improved machine; Fig. 2 is a section on line 2 -2 Fig. 1; Fig. 3is a side elevationwith one of the legs of the main frame broken awayto'show the mechanism; .Fig. 4

The rod 3 is of less diameter than the a tube 4 and of greaterlength, and is surround- ,with two notches 23, and immediately below thetransverse member of the U frame 1 I provide'a locking disk 24pivoted at41 to I the frame 1, and diametrically opposite the pivot provided witha spring 27 resiliently bearing against the disk 24 and fitting into arecess in the frame 1. The spring 27 is preferably a simple coil springand the disk24 is preferably in the shape of a'washer.

To the lower end of the rod 3 I'secure the I numbering wheel frame 9whichis preferably a single piece of metal bent unto U form and ofsu'chstructure or worked into such condi-tion as to cause the free ends ofthe U to tend to slightly approach each other through an inherentresiliency of the body of the U frame 9.

Through the U frame 9 I mount the shaft '40 for the number wheel, whichshaft is preferably of a length equal to the distance between the twolegs of the frame 1, and thus when the machine is assemblednon-removable; merely being held in position by the legs of the fr me 1.A second shart 41 is also secured in are frame 9 and carries thedetaining pawls provided witha spring 14 ofusual construction, while ashaft 42 is also mounted inthe frame 9 to one end of which a spring 43,hereafter described is secured.

Studs 44 on the frame 9 travel in the slots 2 of the frame 1 and onthese studs there are mounted levers 45 pivotedat 38 to second levers 36which are pivoted in the frame 1 by screw'46 engaging threaded holes'37in the lever36, while studs 35 are secured to a U+shaped pad-carrying,frame 34 provided with a notched opening 47 in its lower face and guidedby a groove on its upward ex.-

' tending arms whichembrace the studs 44 in the usual manner, so thatupon the downward mounted a coil spring 31 hearing upoiia lever 80having a nose at one end adapted to engage a notch 47 so that the twoarms 29 and 30 mav. be pressed together torelease the nose oi the lever30 tron'i the notch 47 to allow the withdrawal of the pad 33.

The U-shaped frame 9 is -provideC at its outer ends with projecting lugs48 having slightly underci'it or inclined surfaces, as shown in Fig. 7,while the printing plates 50 are provided with undercut bevel notches 51on their end surfaces, with a cut-out portion 52 on their inner surfacesand with lettering or the like on their so I e 53, so that the may bepushes, vert' i ll down upon the projections ol the l shaped frame andsnapped into place and. held by the res liency of said frame without theuse of screws or awkward holding contrivanee's. These plates 50preferably meet on their center line, as shown in l a, and are out outat 52 to allow for the appearance of the func tioning' characters of thenumber wheels between them.

As shown in Fi 4', when the machine is-in the position indicated and infact in any position in which the pad frame extends substantially asshown in that figure, a screw driver or other instrumen may he used asshown in the dot and dash line, for prying the printing plate out ofposition, in which case the edge of the pad frame will act as afulcrun'i for the instrument. lf it is desirous to remove the other sideplate, the machine is preferably moved and'loched into the positionshown in 5, when the edge of a guard plate 11 hereinafter described willbe in position to act as aiulcrum fora-n impleent pry oil the frontprinting plate.

The guard plate 111's provided. with a central slot 12 through which thelever 18 directly connected to the pawl swing 17 protrudes and isnormally held in the position shown in Fig. 2 by the spring 43,heretofore described. The guard plate 11 is fastened upon the top of theU-l'raine 9 and is pro vided with a depending plate 10 in the rearcarrying the usual forms of plate pawl retaining springs.

On the shaft 40 for the number wheels I pivotally mount the pawl swing17 which straddles the number wheel and which carries a rod on which ispivoted a pawl mechanism comprising two right angular pawls connectedtogether by a stud 61, one of said pawls (pawl 62) having a tooth of awidth equal to the combined width of the ratchets on the tens and monthwheels, while pawl 63 provided with a thin blade portion he providedwith an inwardly turned pawl tooth 65. A spring 66 tends always to movethe ends of the pawl toward the shaft 40 of the machine.

The number wheels for a dating machine consist of onewheel 70 having aratchet wheel 71 pro'vi'dedwith 12 divisions cl teeth to correspond tothe twelve months. The tens wheel is provided with a ratchet wheel 81having ten teeth and of slightly greater diameter than the month ratchetwheel 71. This ratchet wheel 81 is provided wvith' one deep tooth 82penetrating farther into its center than do. the teeth of themonthswheel, so that the pawl 62 when advancing the tens wheel and whenin the deep tooth 82, will also advance the months wheel one tooth, butwhen on the normal teeth of wheel 81 it will ride safely over the monthsratchet teeth and not operate the same. The units wheel is provided witha ratchet wheel 91m greater diameter than the tens ratchet wheel, sothat in all instances, except those now described, the tens wheel willremain inoperative upon the operation of the unit wheel. This ratchet 91is provided at one of its points with a stud or pin 92 in lieu of aratchet tooth, while a deep recess 93 is bridged beneath said pin 92 fora distance of two teeth. immediately preceding this notch 93 is a deeptooth 94. The stud92- is not so long as to interfere with the passage ofthe blade-like part 64: of the pawl 63. To

better understand'the operation oi these teeth and ratchets'l will('lcscrihe their operation for one month, which is as follows: Assumingthe preceding clay to have been June 30th, it will he desired to removethe wheels to Julylst. The operator'moves the lever 18 downwardly initsslot, which causes the pawl 65 to drop into the notch. between thepin 92 and its preceding tooth, to push a unit wheel forward one toothto indicate June 31st. Now as there is no June 81st it will be necessaryto again reciorocate the pawl spring. This time the toot i- 65 fallsbetween the pin 92 and its succeeding tooth, while the pawl 62 fallsinto its deep notch 82, and when in said deep notch it allows the pin 65to pass beneath the stud 92 without moving the unit Wl'LE-Ql, but thetens wheel and the months wheel will together move forward to move thedash 1 into place beside the number 1. Upon the next oscillation of thepawl swing the tooth 65 will again engage the notch 93 but not to thesame depth as the pawl 62 will then been a normal tooth so that the pawl62 and pawl tooth 65 will each move its wheel one tooth producing 2 onthe tens and 2 on the units. tooth 65 will engage a normal ratchet toothof the unit wheel and so continue until the figure 9 is brought intofunctioning position during all of which time the second dash of Uponthe next reciprocation thethe tens wheel will have remained in place,but as soon as it is desired to shift the 9 to zero, the tooth 65 willfall into the doe notch 94 and allow the pawl .62 to move t 1e tenswheel one more unit producing the figure The two successive movementsalso allow the pawl 62 to come into play to shift the two repeatedcharacters 1 forward on their tens wheel, and alike operation takesplace for the nextrotation of the unit wheel to lace the characters 2and 3 in functioning position. A similar operation for the tenscharacter takes place, but it will be noted that there are only two ofthese characters, but as shown in the beginning of this operativedescription when a third shift is to be made after the date 31 the unitswheel isnot moved and the tens wheel is advanced one point, thusbringing the cycle of operation into proper successive advancement ofthe characters and of the months. The year wheel 95 is showndiagrammatically in Fig. 11 and may be hand set.
